RS2596
150KHz, 3A PWM Buck DC/DC Converter
Page No. : 1/9
General Description
The RS2596 is Monolithic IC that design for a stepâdown DC/DC Converter, and own the ability of driving a 3A load without
additional transistor component.
The output version included 3.3V, 5V, 12V and an adjustable type. It operates at a switching frequency of 150KHz thus
allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other
features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions,
and ±15% on the oscillator frequency. Regarding protected function, thermal shutdown is to prevent over temperature
operating from damage, and current limit is against over current operating of the output switch.

Application Circuits
Adjustable Output Voltage Versions
This integrated circuit can be damaged by ESD. Orister Corporation recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
